well after my first "major brand" ram was faulty i returned it and ordered the OWC branded memory.
IT WORKS!!
I have ran rember with zero errors and the computer is experiencing no hangs or flickers. I am going to run a tech tool deluxe later when i go out but as of now it seems to work.
You have restored my faith in you OWC.
Keep us posted please. Give us a week update.
I'm about to get the 8GB and I want the OWC but I'll settle for GSkill if the OWC is still having the issues.
Mine from them in my old MBP worked great.
